SPECIFICATION forming part of Letters Patent No. 715,178, dated December2, 1902.

Application filed December 5, 1901. SerialNo. 84,791. (No model.)

To CLZZ/ whom it may concern:

Be it known that I, GEORGE WASHINGTON TOLER, a citizen of the UnitedStates, residing at Greenville, in the county of Yell and State ofArkansas, have invented a new and useful Cultivator, of which thefollowing is a specification.

This invention relates to cultivators.

The object is to present a cultivator for use in cultivating corn,cotton, or the like in which provision shall be made to cause effectiveremoval of weeds, grass, duc., and for supplying clean earth tothefurrow, at the same time breaking up or dividing the earth, thereby toprevent baking, to provide suitable means by which the disks orcutters'and also a roller used in connection with the device may be heldat the predetermined or desired adjustment, to provide means by `whichthe scraper may be adjusted with relation to the disks or to the rollerindependently of either, and generally to provide a simple, thoroughlyeffective, and durable form of cultivator.

The invention consists in the novel construction and combination ofparts of a cultivator, which will be hereinafter fully described andclaimed.

Generally stated, the cultivator characterized by my inventioncomprises, in connection with a wheel-supporting frame, two sets@ ofdisks oppositely convexed with relation to each other, the disks beingadjustable about a verticalaxis atright angles to their supports, ascraper arranged in front of each set of disks and adjustable withrelation thereto, thereby to cause the scraper to be rendered coperativewith the disks irrespective of the character of furrow cut, and a rollerarranged at the rear of the disks andA adjustable independently of thedisks and the Scrapers, the object of the roller being to overcome sidedraft and to press down the loose earth, thereby to retain moisture.

In the general construction of the cultivator the supporting-frame andadj uncts usually appertaining thereto may be of any preferredconstruction and therefore need no specic description.

The invention resides in the coperative relation effected between theScrapers, the

disks, and the rollers and the means by` which either or all of thesemay be adjusted independently' to render the device thoroughly operativeunder all circumstances.

In the accompanying drawings, forming a part of this specification, inwhich like numerals of reference indicate corresponding parts, Iillustrate a form of embodiment of the invention, it being understoodthat some of the ideas may be carried into effect in other ways withoutdeparting from the spirit of the invention.

In the drawings, Figure I is a View in perspective, taken from the rearof the machine. Fig. 2 is a view in side elevation. Fig. 3 is a view inplan. Fig. 4 is a detail view of one of the Scrapers. Fig. 5 is a detailperspective view of the disk-carrying yoke and the roller-carryin gyoke,showing the clutch mechanism for holding the two yokes in adjustedposition with relation to the supportingframe. Fig. 6 is a longitudinalsectional detail view of the disk-carrying yoke.

Referring to the drawings, l designates an arch, and 2 an axle, thelatter carrying supporting-wheels 3, as usual. The axle may support thetongue, seat, and other parts common to the frame of an ordinarycultivator, and as these form no part of the present inventiondescription is deemed unnecessary.

The supporting-frame of the cultivator mechanism comprises two beams orbars 4, suitably secured' to the arch l, and as the mechanism carried byeach bar is the same a description of one will serve for both.

Working in a suitable guide 5 on the beam 4 is a standard 6, carrying ascraper 7, the

scraper being, in effect, an ordinary moldboard without a landside. n Inother words, in operation it performs the function of a scraper pure'and simple and not that of a plowshare. The scraper is secured to thestandard at an angle to the bar, as usual, and is mountedfor adjustmentin the arc of a circle-that is to say, is capable of a vertical 'ltingadjustment 'transversely ofthe device-thus to cause the cutting edge 'ofthe scraper either tolie parallel to the ground or at an angle thereto.To effect this, the scraper is provided with a series of openings 8,arranged in the arc of a circle, a bolt 9, passing through one of theopenings, serving to hold the scraper in the desired adjustment.Normally the inner edge of the scraper is at an IOO ` scraper.

angle to the faces of the disks, so that the grass, weeds, or the likedetached by the scraper will be thrown to one side. lt will be observedthat in addition to the series of openings 8 there are two otheropenings 10, one of which is permanently engaged by a bolt 1l when thescraper is adjusted for ordinary use; but should it be' desired to bringthe inner edge of the scraper parallel with the standard the bolt 11will be removed from the opening shown and the scraper moved to one sideto bring the other opening opposite that in the standard, and the bolt11 may again be inserted, and the scraper thus held in its adjustedposition. The standard is provided with a plurality of openings 12 to beengaged by a bolt 13, passing through the guide on the side of thestandard, this ar- -rangement being provided for effecting verticaladjustment of the scraper. On the opposite side of the beam to thatoccupied by the standard 6 is another guide 14, engaged by a standard15, the lower portion of which is bent approximately at right angles toits length and supports the disk-carrying yoke 16. The standard 15 isprovided with a plurality of openings 17 to be engaged by a bolt 1S,carried by the guide 14, this arrangement being employed to eifect thevertical adjustment of the disks irrespective of the The manner ofconnection between the yoke 16 and the standard 15 is to be such thatwhen the yoke is adjusted to cause the disks to occupy the desired anglewith relation to the furrows the yoke will be held in this position.Several forms of device may be employed for this purpose, and that shownherein is illustrative of one arrangement that will be effective inoperation and readily applied for use. It consists in providing thebottom of the standard with a serrated face 19 to engage with a similarface 2O on the upper surface of the yoke, a bolt 21 passing through thelower portion of the standard 15 and the yoke to clamp these twoserrated surfaces together. It will be observed by reference to Fig. 8that the yoke 16 is provided with a plurality of openings 22, eachopening being surrounded by one of the serrated faces 20, above referredto.. By this arrangement when the yoke is moved to the desired angle itwill be firmly held in position against shifting. On the inner side ofthe bar is secured a fender 23, the function of which is to prevent thedisks in operation from covering up the small corn or cotton.

Carried by the yoke 16 is an arm 24:,which may be slightly resilient,this arm to be fixed to the yoke 16 in such manner as to move therewith.The arm 24 carries a yoke 25, provided with a plurality of openings 26to be engaged by a bolt 27, the manner of holding the yoke 25 in rigidconnection with the arm 24c being preferably similar to that describedin connection with the holding of the yoke 16 rigid with the standard15. The yoke 25 carries a roller 28, the function of which is to pressdown the loose dirt that has been cut up by thedisk, thereby to preventescape of' moisture.

In the operation of the device the scraperblade scrapes and loosens thesurface of the soil and at the same time cuts and sheds the vegetationtoward the outer side of the device, so as not to choke the barrow-diskswhich are tracked in rear of the scraper and act to cut or chop theloosened soil, and iinally the roller 28 passes over thefinely-pulverized soil, so as to pack or press the same and therebyprevent the escape of moisture.

It will now be understood that the present device is intended to breakup and pulverize a comparatively thin surface layer. of the soil, andfor this reason employs a gang or plurality of comparatively small diskswhich travel in the track of the scraper and act upon the soil which hasbeen loosened by the scraper, wherefore it will be understood that thedevice is not intended for and is also incapable of turning a furrow,but is arranged to break up or pulverize a thin surface layer of soil.

In some sections of the country where there is what is known asblack-wax landthat is to say, a soil that is heavy and sticky-thescraper may be removed and a second series of disks, carried by asuitable standard, be placed in front of the usual disks and held inplace by the guide occupied normally by the scraper. It will beunderstood that the disks will be oppositely conveXed, so that IOOr oneset of disks will throw the earth from the cotton or the like and theother to the cotton or the like, the fender in the manner describedpreventing any covering up of the cotton or corn.

It will be observed by the manner in which the differents parts areassembled with relation to the supporting-frame that each part isadjustable independently of the other, and by this manner of arrangementall conditions arising in the use of such a cultivator will be providedfor. Although not shownin the drawings, l contemplate providing scrapersto remove accumulations of soil from the disks and the covering-rollerswhen the cultivator is being used upon heavy and sticky soil, saidScrapers to be of any well-known or preferred form.`
